MACHINE FOR THREADI'NG TAPE IN TO EDGING.

eI-ECIFICATION forming part of Letters Patent No. 730,255, dated June 9, 1903.

Application filed April 12, 1902.

To ctZZ whom, it may concern: I

Be it known that I, DAVID GROTTA, residing at Newark, in the county of Essex and State of -New'Jersey, have invented certain new and useful Improvements in Machines for Passing Ribbon Through Lace, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for passing ribbon or tape through lace or edging to be used on wearing-apparel, especially corsets.

The present inventionis an improvement on the machine invented by me and described in my prior application for patent, Serial No. 7 0,451, filed August 1, 1901, and relates especially to the spur or sprocket roller used to string the edging onto the needle by which the tape is inserted in the edging. In my prior machine the series of spurs were not adjust- The spurs were so placed .on the roller that one roller would operate only on pieces of edging having the opening therein spaced the same distance apart. WVhen tape was to be inserted in edging having the openings differently spaced from those in a piece for which the roller was made, that roller would have to be substituted by another. In other words, it was necessary to have separate rollers with spurs thereon spaced to correspond with the openings in the edging. This was expensive and undesirable. Not only this, even when the spurs were spaced to correspond witha piece of edging having the openings spaced a certain distance apart good results could not be obtained, owing to the fact that the distances between the holes in forth in the specification.

The invention will be understood by those skilled in the art from the following specification, taken in connection with the accompanying drawings, forming a part thereof.

Referring now to the drawings, in which like letters of reference indicate the same parts in the different views, Figure 1 is a horizontal vertical broken section taken lengthwise of the machine. Fig. 2 is a vertical transverse section taken on line 2 in Fig. 1.

Fig. 3 is an end View of the roller, showing the cam-plate for adjusting the plates carrying the spurs. Fig. 4 is a perspective view of one of the plate-carrying spurs. Fig. 5 is a side elevation of the machine on a smaller scale than shown in the prior figures. Fig. 6 is a plan view of Fig. 5; and Fig. 7 is a plan view of a piece of edging, showing the tape or ribbon passed therethrough.

In the drawings the part lettered A represents the bed of the machine, having raised guides B B on each side thereof, between which the insertion or edging passes after it leaves the rollers. 0 .represents the guides for guiding the edging before'it enters the rollers, these guides being pivoted to links 0, so that they may be adjusted for different widths of edging. D is the roller mounted on the bed of the machine. E is a guide-rolllocated above the rollerD and journaled in the frame pivoted to a bracket on the machine. This roll is grooved at E, into which the spurs on the roller D enter. I and J are clamps to hold the needle Kin proper position. At one end of the bed of the machine is attached the bracket 0 to support the spindles on the feedroll'Oiwhich carries the insertion or edging 0 having openings 0 through which the tape L is to be inserted. Pis atake-up roll journaled in brackets at the other end of the machine and which may be operated by a handle P Q is an adjustable guide pin or roll adjacent to the roller D and under which the insertion passes before it is taken up by that roller. All of these parts except the roller D are substantially the same as those shown in my prior application.

The roller D, which consists of certain adjustable parts and which is the subject-matter of my present invention, will now be described: I

D is a shaft on which the roller is mounted;

the spur-teeth.

D is a sleeve loosely surrounding the shaft and having secured to each end thereof a disk D which is provided with a series of radial slots (Z On the outside of each of these disks D is another disk, D", which is secured to the shaft D. Each of these disks D has a series of cam-shaped slots (1* therein, as shown in Fig. 3 of the drawings.

D represents a series of plates, 011 each of which is secured one of the spur-teeth D, which is slotted, so as to leave an incline or cam-surface D at the bottom thereof. Each end of this plate is bent at right angles, as shown at D D is a transverse rod extending across the plate D and projecting through the ends D thereof. Each of the ends D of this rod extends just through the radial slots D is another rod passing transversely across the plate and having the ends D thereof pro j ecting through the ends D and are of such length that they will extend through the slots 51 in the plate D and through the slots (Z in the disk D These rods D and D are for the purpose of guiding the plates D when the plates are to be moved in and out to adjust One of the rods D has an end D of such length as to project beyond the outer face of the disk D*, and is screw-threaded to carry a clamp-nut D used to clamp the disks D and D together, for the purpose to be hereinafter set forth.

D is a tongue secured to the under side of the plate D just under the spur D to hold the needle in its operative position.

D is a slot in the plate D which registers with the slot in the spur D and in which the needle is guided when the roller is in operation.

\Vhen the parts of the roller are assembled, as shown in the drawings, the distance between the spurs may be adjusted so as to cause the spurs to take into edgings having the holes therein at different distances apart by moving the outer disks D \Vhen these disks are moved, which may be done by turning the shaft on which they are mounted, the cam-slots 1" therein, operating against the ends D of the rods D, will move the plates D toward or from the center of the disk, depending upon the direction in which the disk is moved, and the plates will be guided by the rods D and D moving in the radial slots d Then the plates are moved out, it is apparent that the distance between the spurs will be increased and when they are moved in it will be decreased. hen the spurs are set to their proper position, the clamp-nut D is turned to clamp the two plates D and D together, so that they cannot be moved independently of each other, and the plates D will then be held in their set position. Vhen the shaft D is rotated to turn the roller D in the direction of the arrow, which may be done by applying power to the pulley F on the end of the shaft, and the cam-surface D of a spur comes under the end of the needle, it will D carried by the next plate D raise this end so as to cause it to pass through one of the openings in the edging. As this spur passes from under the end of the needle the needle will drop and enter the next opening in the edging and rest upon the tongue This tongue holds the end of the needle up, so that the needle will not fall between the plates D when the plates have been moved out to such a distance from the center that their edges do not meet and form a continuous bearing-surface for the end of the needle between the spurs. As the needle rests on the tongue D upon a continuous rotation of the roller the tongue will pass from under the end of the needle and the slot D in the next plate will come under the end of the needle and guide it on the cam D of the next spur D and raise the needle up through the next opening in the insertion through which this second spur projects. It is understood, of course, that the slot D is in such position in the plate D so that it registers with the slot in the spur D, and it is on the same longitudinal plane as the needle. The continued rotation of the roller will cause the end of the needle to alternately pass up and down through the holes in the insertion and string the edging on the needle, so that the tape L is passed through the openings in the edging in the manner set forth in my prior application.

As the present invention relates solely to the roller and especially to the adjustable feature thereof, and as with this exception the machine operates the same as that described in my prior application, it is believed that no further description of the machine here illustrated needs to be set forth.

, WVhile I have shown a particular form of means for adjusting the distances between the spurs, yet it is to be understood that I do not limit myself to the construction here shown and described, as many changes and modifications may be made without departing from the spirit of my invention. As I. am the first, so far as I know, to provide a roller for this class of machines with adj ustable spur-teeth, so that it will not be neces sary to change the rollers for every piece of insertion that may have openings therein spaced at a different distance from another piece, I am entitled to claim such feature broadly.
